Musk Ox

It is the only animal to live in the extreme north i.e. Arctic region. The different areas in which musk ox is found are Sweden, Norway, Siberia, Greenland, Canada, Ellesmere Island, and Alaska. The 24 inch long hair of this animal protects it from the cold weather of Arctic tundra. The musk ox can reach the body length up to 7 feet, while its weight ranges from 396-880 lbs. This herbivorous creature is known to feed on stuff like willow, bearberry, crowberry, etc. The musk ox lives in herds and every group/herd has a dominant male (bull).

The polar bears also feed on lemmings, ducks, Arctic foxes and carcasses of walrus. The population of polar bears, owing to massive hunting, had reduced to mere 5000.

Adaptations

The Arctic tundra plants and animals have to adapt themselves in order to survive the harsh conditions of this region. For example, caribous possess hooves that are large and spreading. Balance of the body is maintained with these large hooves, as the caribou traverses marshlands and snow-clad areas. One of the special characteristics of these animals is that the body’s metabolic rate can be lowered in harsh weather; it is kind of a semi-hibernation condition. The thick blubber layer (4.5 inch.) protect polar bears from the extreme cold weather (as low as -34 °F). The hollow hair shafts of the fur of this animal also provide excellent insulation.

Few of these creatures have become endangered owing to the effects of global warming and human interference in this region. It is therefore, important to protect the fragile ecosystem of tundra biome and the world as a whole.
